Worth knowing
Rules that come up in this work
Switching accountants
You can switch accountant at any point in the year. The new firm requests clearance and your records from the old one, which cannot withhold your own documents though it may hold its own working papers until its fees are settled. Agent authorisations with HMRC and Companies House are transferred, and the next deadline is picked up without a gap.
Closing a company
Striking off a company is cheap but must be done in order: stop trading, file the final accounts and CT600, pay the tax, close VAT and PAYE, distribute the remaining assets, close the bank account, then apply. Anything left in the company at dissolution passes to the Crown. Distributions up to £25,000 are taxed as capital gains; above that a formal liquidation is usually needed to keep capital treatment.
Dormant companies
Dormancy is a status that is easy to lose. The strict rule is no accounting transactions other than share capital and Companies House fees, which means no bank account activity at all in practice. Fees should be paid personally by the director. A company that traded and has stopped becomes dormant only after its final trading accounts and tax return are filed and HMRC is told.
The trading and property allowances
Not every small income needs a tax return. The trading allowance exempts the first £1,000 of self-employment or casual income and the property allowance does the same for rental income, each measured on gross receipts. They cannot be combined with rent-a-room relief on the same income, and claiming the allowance means giving up the expense deduction for that source.
Employer National Insurance
Since April 2025 employer National Insurance has been 15% on earnings above a £5,000 secondary threshold, a substantial increase for small employers. The Employment Allowance rose to £10,500 at the same time to soften it for the smallest businesses. Directors deciding their own salary weigh this cost against the Corporation Tax deduction a salary provides.
Workplace pensions and auto-enrolment
Workplace pension compliance is part of payroll, not separate from it. Each pay period the payroll assesses who is eligible, calculates employer and employee contributions on qualifying earnings between the lower and upper thresholds, and sends the contribution file to the scheme. The minimum total is 8%, and many employers choose to contribute more as a recruitment advantage.
Record keeping
Good records are the difference between a quick enquiry and a long one. For the self-employed, five years after the filing deadline; for companies, six years from the year end; for VAT, six years. Photographs of receipts, PDF statements and software exports all count. The requirement is to keep records, not paper, and a well-organised cloud folder satisfies it.
Questions
Cash-Flow Forecasting questions from Portsmouth
What is in the funding-application pack?
For £299: a 12-month forecast with monthly cash flow, profit and loss and balance sheet, an assumptions schedule, sensitivity analysis showing what happens if sales fall or costs rise by set percentages, and a narrative explaining the business and the use of funds in the terms lenders and grant bodies use. We brief you on the questions they will ask.
Will banks accept your forecasts?
Yes. Lenders see forecasts constantly and recognise one built from real data with documented assumptions. Grant bodies and investors likewise. We produce covenant calculations and any specific format a lender requires, and we are happy to speak to the lender with you about the assumptions.
Why do forecasts usually go wrong?
Three reasons: they assume customers pay on the due date, they forget tax dates, and they are never updated. We model actual payment behaviour from your history, place VAT, PAYE, Corporation Tax and Self Assessment payments on their real dates, and offer the refresh retainer so the forecast stays current.
Do I need bookkeeping with you to have a forecast?
No, but the data must exist. We build forecasts from any reasonably kept accounting file plus bank data. If the bookkeeping is behind, we say so first, because a forecast built on stale records is worthless. Clients in our bookkeeping service have the data ready by default.
What is a 13-week rolling forecast?
A week-by-week projection of cash in and cash out for the next quarter, built from your debtor book and payment patterns, your creditors and their terms, payroll, rent, loan repayments and every tax date, giving the forecast bank balance at the end of each week. It is the standard tool for managing short-term cash and is refreshed as actuals arrive.
How is the £199 forecast built?
From your bookkeeping and bank data, your aged debtors and creditors, your payroll, your known commitments and the tax calendar. We analyse how quickly your customers actually pay rather than when they are due, which is where most forecasts go wrong, and we document every assumption so you can change it. You receive the model and a short briefing.
